Objective  To develop and validate a self-reported outcomes measure for patients with sleep-disordered breathing—the Snore Outcomes Survey.

Design  Item areas of the SOS were developed by an expert panel. Consecutive patients were enrolled into the study in a prospective manner. Patients received the SOS, the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index, the Medical Outcomes Study 36-Item Short-Form Health Survey, and standard overnight polysomnography at baseline and after 4 months of continuous positive airway pressure therapy.

Setting  A tertiary care, academic otolaryngology and sleep disorders referral center.

Patients  One hundred fifty-six adult patients presenting with a chief complaint of snoring or sleep-disordered breathing to the Massachusetts Eye and Ear Infirmary, Boston.

Main Outcome Measures  Test-retest reliability, intrasurvey reliability, internal consistency, validity, and standardized response means of the SOS.

Results  Overall, reliability of the SOS was excellent (test-retest reliability r = 0.86; P<.001; Cronbach coefficient, 0.85). The SOS index significantly correlated with the Epworth Sleepiness Scale (r = - 0.42; P<.001) and the global Pittsburgh Sleep Quality Index score (r = - 0.38; P<.001), as well as with the number of recorded arterial oxygen saturation levels below 85% (r = - 0.46; P = .02). The SOS index was sensitive to clinical changes after intervention (standardized response mean, 0.57).

Conclusion  The SOS is a reliable and valid instrument for assessing sleep-related health status for patients with snoring and sleep-disordered breathing and for measuring change in health status following therapy.
